BLOCK-MACHINE.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed July 7,1906. Serial No. 325,081.

To all whmn it may concern.-

Be it known that I, HENRY G. GRIsIER, a cltizen of the United States, residing at Stryker, in the county of lVilliams and State of Ohio, have invented a new and useful Block-Machine, of which the following is a specification.

This invention relates to a mold and means for readily varying the size of the form as well as quickly and conveniently discharging.

This invention has utility when adapted to block machines for making building blocks, and is especially desirable owing to the ease with which it may be adjusted to produce blocks of different lengths, as lintels.

Referring to the drawings; Figure 1 is a front view, in perspective, of an embodiment of'the invention in a block machine, parts being broken away to better show certain features. Fig. 2 is a rear view, in perspective of the same machine. Fig. 3 is a detail of the selflocking wall-actuating means. Fig. 4 is a detail of an end wall, showing its adjustable mounting and locking device, and Fig. 5 is a section on the line VV Fig. 1 looking in the direction of the arrow.

Supported on the legs 1 is the angle bar rectangular frame having the end bars 2 and front side bar 3 and rear sidebar 4. Spaced a short distance from the angle bar 4. and connecting the end bars 2 is the angle bar 5. Extending between the bars 3 and 4 and supporting the bar 5 intermediate its ends, are the braces 6. These braces 6 have later ally extending lugs 7 at their ends by which the braces are connected to the bars 3 and 4. These braces also serve to support one end of the guides 8, which guides 8 have their opposite ends connected to the end bars 2. Also extending across the frame, and medially thereof is the hanger 9, having mounted therein the wheel 10 which is supported below the level of the frame. Oppositely connected to the wheel 10 are the two curved links 11, pivotally connected at their opposite ends to the rods 12. The rods 12 are guided by openings in braces 6 and end bars 2. Adjustably mounted on each rod12 is a bracket 13, which has extensions to slide along the guides 8 to thereby properly carry the wall 14 mounted on the bracket 13 in its straight line movements. Loosely pivoted on the end wall 14 is the lock bar 15 which has near its ends inclined portions 16, so that when rocked by the handle 17 into locking position, these inclines 16 will so engage hooks on the side walls of the mold as to firmly draw the parts into proper relation.

Extending from the wheel 10 is the arm 18, connected by the link 19 to the operating lever 20, pivoted to the bar 4. From its pivot 21, the lever 20 extends under the frame and out on the opposite side, to give good leverage. A guide 22 for the lever 20 is mounted on the bar 3. The operating lever 20 may be actuated by the foot of the workman.

In the mold, the bottom side 23 is shown as the rock face. The mold side 23 is carried by arms 24, adjustably fixed to rock shaft 25. When the mold is closed, the ends of the arms 24 remote from shaft 25 rest on angle bar 5, thereby firmly holding the side 23.

Loosely mounted on the shaft 25 adjacent to the arms 24, are arms 26, having recessed portions 26, whereby in rocking the shaft 25 to carry the wall 23 outward, the arms 26 are also moved and ninety degrees ahead of arms 24. However, after opening, the shaft 25 may be rocked back slightly before engaging arm 26, thereby permitting the wall 27 car ried by the arms 26 to be slightly more than ninety degrees from Wall 23 and so free the block that it may be readily removed. In compactness of construction and certainty of operation this recessed arm characteristic is of considerable value in accomplishing the freeing or releasing of the block.

The wall 27 has openings 28 therein. The opposite wall 29 has opposed openings 30. Through these openings, cores 31 are guided in the molding of hollow building blocks. The cores 31 have extensions 32 guided in the yoke 33, removably mounted on the angle bar 4 and angle bar 34, which latter is mounted between legs 1 and below the rectangular frame. Pivotally mounted on-the yoke 33 near bar 34, is the operating lever 35, extending well forward toward the mold, so that the machine operator may from his po sition in front of the machine, reach over and through the hand lever 35 move the cores 31 into or out of the mold, the cores being connected to the lever 35 by the link 36, which in this instance for two cores, is shown as T-shaped. I

To hold the side wall 29 are brackets 37 removably attached to the wall. These brackets 37 are slidable to various positions between the bars 4 and 5, being held from tilting outward by the block 38, removably locked to bracket 37 under bar 5.

IIO

Mounted on the rock shaft 25 is the operating lever 39 which may be placed along the shaft as convenient, either within the limits of the frame, or on the shaft extended beyond. The walls are all readily removable, permitting of the convenient substitution of various designs and different sizes. The adjustment of the walls 14 takes care of dif ferent lengths While the adjustment of arms 24 and 26 and brackets 37 accommodates the variations in side walls.

Through lever 20, link 19 and arm 18, the disk or wheel may be oscillated. As shown in Fig. 3, when the end walls 14 are drawn to closed position, the wrist pins of links 11 on wheel 10 are by their dead center positions, and pressure on the end walls 14 in charging the mold will not serve to force the end walls from the self-locked position. Oscillation of wheel 10 serves to simultaneously move walls 14 in opposite directions along a common straight line uniformly from the rest of the mold.

The embodiment of the invention shown is a neat, simple, compact and efficient device. However, the idea of the invention herein ings and description to any reater extent than the ordinary meaning of the terms of the claims demand. In other words, the elements set forth in the claims are to be interpreted broadly, giving me the advantage of equivalents in the protection of my idea.

What is claimed and it is desired to se cure by Letters Patent is: y

1. A mold having block freeing mechanism comprising a fixed side wall, a core movable therethrough, simultaneously slidable end walls, recessed pivoted arms, a dischargedblockreceiving side Wall carried by the arms and a pivoted bottom wall having its movement relative to the side wall limited by engagement with the walls of the re cessed arms whereby on tilting the side wall outward the bottom wall may move away from the block.

2. A block machine comprising a rock shaft, a mold having a wall fixed to the shaft,

recessed arms carried by the shaft and a second wall loosely mounted on the shaft and having means engaging in the recessed arms to limit relative movement of the shaft car ried walls, whereby in discharging the block from the machine upon the side wallthe bot tom wall may be freed from the block.

In testimony whereof I aflix my signature in the presence of two witnesses. disclosed is not to be limited by the draw- 1 HENRY G. GRISIER;
